OIL-BURNER.

. To all whom t may concern Be it known that I, WALTER M. SURFACE,

`a citizen of the United States,\residing at Kingman, in the county ofVKingman and Stateof Kansas, have invented a new and of which the`following is a specification.

` The present invention appertains tooil orhydrofcarbon burners, andaims to provide a novel and improved device of that character.`

The present invention contemplates the provision of a hydrocarbonburnerl of unique construction, which will possess two atomizing means,for thoroughly atomizing of steam or other pressure uid, and whereby`the combustion of the mixture will be of a high order. A Another objectof the present invention is to provide a hydro-carbon burner whereinmeans is provided for controlling the ame, whereby the length of theflame may be varied as well as the width of the flame, and whereby theflame may be directed in various directions, as desired. It is alsowithin the scope of the present invention to provide in an appliance ofthe present character, such a combination and assemblage of thecomponent parts, as to enhance the utility of the burner. y

With the foregoing general objects outlined, and with other objects inview, which will be apparent as the nature of the invention is betterunderstood the invention resides in the combination and arrangement ofparts and in the details of construction hereinafter described andclaimed, it being undei-stood that changes in the precise emhodi` mentof the invention` herein disclosed, can be made within the scope of whatis claimed,

` without departing from the spirit ofthe invention. i

\ Theinvention has been illustratedlin its preferred embodiment `in theaccompanying drawing, wherein:- p i y i.

tion'. As illustrated, the body 1 comprises a rear section 2 and anintermediate section 3, which are connected by means of an innercoupling or sleeve 4 threaded into the adjacent ends of the sections 2and 3. The body l further includes a forward section 5 threadedly orotherwise engaged to the forward end of the intermediate section 3, and

providing with the intermediate section, a

mixingchamber 6.

The forward or outer end of the body l, or the forward section 5thereof, is provided with areduced outlet 7, preferably in the form of anozzle or nipple, and a hollow burner head 8 is threadedly or otherwiseengaged over the outer or free end of the nozzle or nipple 7. The burnerhead 8 is preferably circular in plan, and has its back wall engaged tothe nipple or nozzle 7, the top and bottom 9-9 of the burner head 8being preferably removable. The front wall of the burner head 8 isprovided with an arcuate slot 10 lying in the horizontal plane in which`the axis of the body 1 and nipple or nozzle 7 lies. The head S providesa secondary mix ing chamber which communicates with the 4 riinar mixinchamber and from which the final mixture is adapted to pass to supportcombustion, as will. hereinafter more fully appear.

Threaded or otherwise engaged into the rear or inner end 'of the body l,or the rear section2 thereof, is a plug or annulus 11 having a centralopening 12, which coperf `ates with 1 a partition or diaphragm 13`formed within the collar 4f, to provide a steam chamber 141 within therear section` 2. The partition or diaphragm 13 is provided withapertures or openingsla adjacent the `rim or collar 'r, and is providedwith a central threaded opening through which is threaded the forwardend of an oil tube or` pipe 15 passed through the opening 12 of the.ring or annulus 11. The oil tube or pipe 15 thus passes axially throughthe steam chamber la, and preferably has a nozzle or nipple 16 threadedor otherwise engaged within `its forward end, to serve as a con-`stricted outlet for the oil or fuel. A jam or binding nut 17 is threadedupon the rear end portion of the tube or pipe 15 and bears against therear face of' the ring orclosure 11, to close the opening `l2 in thering or annulus 11, should the tube or pipe 15 fit loosely within thesaid opening, the nut-17v also locking the tube or pipe 15 in place.

I A controlling valve 18 isv connected to the rear end of the fuel tubeor pipe 15, and has attached to the lower end thereof, a liquid fuelsupply pipe 19 leading to any suitable source of fuel, whereby the fuelmay be fed by gravity, or under pressure, which ever is desired.Thevalve 418 thus serves as a coupling for connecting the liquid fuelsupply pipe 19 and the discharge tube or pipe 15, and also serves tocontrol the flow of liquid fuel into the tube or pipe 15.

Steam or other pressure fluid is supplied into the steam-chamber 14, bymeans of a pipe section 20 threadedly or otherwise engaged through thetop or crest of the rear section 2 of the body 1, and having a valve 21engaged .thereon for controlling the flow of steam or pressure fluidinto the chamber 14. A coupling 22 is attached to the upper end of thevalve 21, for the connection of the steam supply pipe 23.

In order to supply steam or pressure iuid to the burner head orsecondary mixing chamber 8, depending pipes 24 having their 25 upperends connected to the opposite sides of the coupling 22 above thecontrolling valve 21, and have valves 25 attached to their lower ends.Horizontal or longitudinal i pipesr 2G have their rear Aends connectedto the valves 25, the said valves serving as couplings between the pipes24 and 26, and the forward ends of the pipes 26 are threadedly or.otherwise engaged through the rear portion or wall of the head or case 8adjacent the nipple or nozzle 7. The forward end portions 27 of thepipes 26 converge at the sides of the nipple or nozzle 7, and aredirected to the center of the head 8, in adf vance of the nipple ornozzle 7. The for* 40 ward end portions 27 of the pipes 26 serve asnozzles for the discharge of steam into the burner head 8 to provide asecondary atomization of the fuel, as will hereinafter more fullyappear. The pipes 26 have interposed therein, couplings 28, which enablethe sections of thepipes 26 to be readil-y detached and attached for thepurpose of separating or assembling the structure.

From the foregoing, taken in connection with the drawing, it will beobvious that the present apparatus may be readily assembled, and appliedto a steam boiler, stove, or other structure to be heated.

In operation, supposing the auxiliary steam valves 25 to be closed, andsupposing the main steam valve 21 to be open, it will be obvious thatthe steam will be admitted from the steam supply pipe 23 into the steamchamber 14, so as to be discharged through the apertures or outlets 13ain the partition 13 at the forward end of the steam chamber 14, into the`mixing chamber 6. y The streams ofsteam or pressure fluid issuing fromthe yapertures 13a will pass over the sides and free end of the nozzleor nipple`16 of the fuel pipe 15 thereby tending to create a vacuum inadvance of the nozzle or tip 16, whereby when the oilvalve 18 is opened,to admit oil Vinto the pipe 15, the'oil or other fuel will be suckedinto the mixing chamber Y G, so as to commingle with the steam, andbecome atomized or vaporized. The fuel pipeV 15 being disposed withinthe steam chamber 14, will become heated by the steam,

.so as to give an initial heat to the fuel, prior 7.5

to the atomization or vaporization Vofthe fuel within the mixing chamber'6. -The pressure of the steam will force the lmixture from the chamberthrough the nozzle or A* nipple 7 into theburner head8,and thence 8'0through the slot or discharge openinglrwto support combustion, the flamebeing ignited in any suitable manner. A When `the valves 25 are closed,as above indicated, the combustible mixture issuing from the nozzle ornipple 7 from the mixing chamber 6, will be thrownV forwardly oroutwardly with considerable force, so asto provide a relatively longflame. Now, to

provide a secondary atomizing action of the 9c,` Y

fuel, the valves 25 are' opened, whichwill aclmit steam from the supplypipe 23 intojthe steam pipes 26, the steam being discharged into theburner head 8 through the nozzles p 27 of the pipes 26. The convergingstreamsv 95 of steam issuing from thejnoz'zles 27.',will intercept thestreamy of thef mixture issuing from the nozzle or nipple 7 from themixing chamber 6, and as a consequence, a second atomizing action willtake'` place within the 1'00 burner head 8, tendingV to morethoroughlyatomize the fuel r`consisting ofa mixture of steam and oilpassing through'the nozzle or nipple 7 intothe burner head 8. Infthismanner, a double atomizing` lfunction is ac- 1'05 complished by thelpresent `burner,in` order that the inal mixture vpassing' through. theoutlet 10 of the burner `head 8, lwill 1 be thoroughly combustible, tovattain a maximum heating eifectwith a minimum amount of fuel, and'with aminimum amount'of soot. The auxiliary supply 'of live steam into theburner head 8" from the converging nozzles 27, is employed las animportantfactor for controlling the flame` or iiames. AThus,f3 1; byproperly controlling the opposite valves 25, so as to vary the streamsof steam issuing from the opposite` nozzles 27, ther pressure of the twoauxiliary streams of steam may be `varied or regulated, lfor'controlling the 110' flame. When the `auxiliary vstreams of steam; areof equalpressure, the flame will be directed longitudinally, vand willbe spread laterally more or less, according to the pres-y sure of thevauxiliary streams of steam, Thus, when the auxiliary streams of steamVhavelittlepressure, they will notspread the flame to anyappreciableextent, andwill not decrease the length of the flame materially.

However, when the auxiliary streams of 13e `eating the flame will covera greater area.

`Another salient or cardinal feature resldes in the fact that when theauxiliary streams of steam issuing from the nozzles 27, are of differentpressures, the flame will be thrown to one or the other side, as will beobvious. This result is accentuated when one of' the valves 25 isclosed, while the other is opened more or less, so as to direct theflame toward the other side. It is thus an easy matter for the operatoror attendant to control the flame to suit the conditions desired, thevalve 18 controlling the intensity of the flame, by regulating the flowof the fuel, which may be of any character, such as crude oil, refinedoil or the like. The size and shape of the fla-me may be controlled to anicety, by properly manipulating the valves 21 and 25, as will beapparent from the foregoing.

The other advantages and capabilities of the present invention will beobvious to those versed in the art, without further comment beingnecessary.

Having thus described the invention, what is claimed as new is l. In ahydro-carbon burner, communicating primary and secondary mixingchambers, a pressure fluid chamber communiwith` the primary mixingchamber, fuel supplying means communicating with the primary mixingchamber, valve-con- Gopies of this patent may he obtained for ve centseach, by addressing' the Commissioner of Patents,
